Description

Description: TECHNICAL FIELD The present invention relates to an electronic organizer having an electronic processing function.

[Prior Art] In recent years, since IC cards and large-capacity memories have become readily available, ROMs and RAMs are made into card types as disclosed in JP-A-62-107360. Electronic notebooks have been proposed for use in various applications by replacing a card with a portable case. In this case, if various ROMs in which different data are written are prepared, they can be used for various purposes only by replacing the card. However, this device has a fixed input device and is not expandable.

In order to solve this problem, it is conceivable to attach an expansion card to the expansion card attachment, but in this case, it is necessary to perform communication between the main unit and the expansion card. Contactless communication is desirable. As an example of performing non-contact communication, a means by electromagnetic induction is disclosed in Japanese Patent Application Laid-Open No. 62-213429. This is because the transmitting side transmits different frequencies at the “1” level and the “0” level, the receiving side always oscillates a certain frequency, and oscillates when there is an input of a frequency synchronized with this frequency. Is reduced, and this is AM-demodulated to obtain a signal.

[Problems to be Solved by the Invention] However, in such a conventional device, regardless of the presence or absence of transmission data, the receiving circuit generates an oscillating output. There is a problem that it is not suitable for a portable device having a limited battery capacity.

[Means for Solving the Problems] In order to solve such problems, the first invention is a method in which a plurality of rings divided from the center and a desired opposed one of these rings are magnetically and dynamically coupled to a magnetic field. And an expansion card mounting device, which is formed of a winding wound so as to cause the expansion card to be mounted by passing the ring through a through hole provided in the expansion card, and provided on the expansion card. An air-core coil provided in a through-hole through which the wound ring of the winding passes, and a periodic pulse provided in each of the main body and the expansion card for a first level. And a pulse generating means for transmitting a signal and generating a pulse signal having the same level as the second level for the duration thereof.

According to a second aspect of the present invention, there is provided a modulating means for modulating at least a pulse having no level change with a pulse signal having a period shorter than the period.

[Operation] Since the electrical state does not change on the receiving side except when there is a state change, power consumption is extremely reduced by using a circuit element such as a CMOS, for example.

FIG. 1 is a perspective view of an electronic system organizer according to an embodiment of the present invention. In FIG, 1 is a portable electronic organizer main body 1 ₁ is a display unit, 1 ₂ cursor keys 1 ₃ function keys, 1 _4, 1 ₅ IC card, 1 ₆ is a power supply. The main body 1 has a CPU (not shown) therein, and has a function of processing input data.

2 is an extended card attachment, which open and close the ring 2 ₁ and the ring 2 ₁ is mounted the recording sheet 3 closing bracket
It consists of 2 ₂ . Reference numeral 4 denotes an expansion card.
The transmission and reception of necessary data with the communication device are performed by communication means described later.

Embodiment Corresponding to Claims FIG. 10 is a perspective view showing an embodiment of the present invention, in which an expansion card mounting device 2 is separated from the center, and an expansion card is mounted therebetween. Of the ring 2 _1, in which wound a coil for electromagnetic induction in the most middle side ring. The coils are individually wound around the right and left rings as shown in FIG. 11, and the respective winding directions are such that the magnetic fields generated by the respective coils act in harmony.

FIG. 13 is a circuit diagram of a transmission circuit and a reception circuit for transmitting data via the communication means configured as described above. The feature of this circuit resides in a portion composed of transistors Q1 and Q2, resistors R3 and R4, a diode D1, coils L1 and L2, and a capacitor C3. To transmit information by electromagnetic induction,
It is desirable that the current flowing through the coil be large. However, this circuit is assumed to be driven by, for example, a coin-shaped lithium battery. However, this battery cannot flow a large current, and forcibly flowing a large current leads to deterioration of the battery. In order to cover this problem, the resistor R3 is for example 270
Ohms, resistor R4 is set to 56 ohms, and capacitor C3 is set to 10,000 PF, effectively solving the problem.

That is, the capacitor C3 is charged with a small current through 270 ohms of the resistor R3, thereby reducing the load on the battery. On the other hand, when the capacitor C3 is discharged, a large current flows through the coil L1 via 56 ohms of the resistor R4 to generate a large magnetic field.

Signal transmission through this circuit is performed as shown in FIG.
A data pattern of a total of 11 bits including a level start bit 1 bit DO-D7 data bit, a parity bit 1 bit, and a level stop bit is transmitted.

FIG. 15 is a diagram showing how each bit is transmitted. Only the "0" level portion of one bit shown in FIG. 15A is finely modulated as shown in FIG. Is transmitted via a coil as shown in FIG. Then, on the receiving side, it is digitally converted as shown in (d),
The data is extracted as received data as shown in FIG.

FIG. 16 is a block diagram of a portion for transmitting a signal via the coil, and this portion is a characteristic portion of the present invention. In the figure, 10 is a clock circuit, 11 is a control circuit, 12 is a switch circuit, and 13 is a demodulation circuit. The control circuit outputs a signal shown in FIG. 15 (b) according to an information signal. That is, when the information signal is at the “0” level, during the period, 1 level and 0
A pulse signal whose level is alternately repeated is transmitted, and when the information signal is at the "1" level, a signal in which one level continues during the period is output.

The message specification is as follows. First, the basic message has a command-logical address-data sequence-message end-BCC configuration except for some messages from the main unit to the expansion card and some from the expansion card to the main unit. If there is no data string,
Alternatively, if the data length is fixed, message end and BC
C is omitted. The BCC is an exclusive OR of all data from the command to the message end.

Another Embodiment FIG. 2 is a view showing another embodiment, showing a display unit.
FIG. 3 is a block diagram of a main part. In FIG.
The display unit is a touch panel, and necessary processing is performed by touching a predetermined portion with a finger in accordance with the contents of instructions on the screen. FIG. 2 shows an example in which the keys of the portion selected by the coordinate range designation signal are displayed in this manner. When only the keyboards of A, B, C, D, and E are required, as shown in FIG.
Only that part is displayed and displayed in a form that is easy to use.

Figure 3 is a circuit for outputting a key code, the arithmetic processing unit 1 _12, the coordinate input unit 1 _13, the input coordinate extraction unit 1 _14, table 1 _15, is composed of the memory 1 _15, the arithmetic processing unit 1 ₁₂ coordinates A range designation signal and a key code extraction instruction are supplied.

Coordinate range designation signal is one of the signals carried what displayed on the display unit 1 _1, for example, key A is an example of FIG. 2, B, C, D, E
Is a signal for displaying the range. The display unit is divided into 50 blocks Ia to Xe as shown in FIG. Here, since the assignment of each key is assumed to be a rectangular parallelepiped key, the range of each key can be specified by the upper left coordinate value and the lower right coordinate value of the key. In FIG. 2, if the coordinates of the horizontal axis of the screen are defined as 0 to 99 and the coordinates of the vertical direction are defined as 0 to 49, the coordinates of the key A are (left 4, upper 5);
Below 15). The method of dividing the blocks is arbitrary,
In the example of the figure, a block having a size of 10 in both the vertical and horizontal directions is assumed to be one block. For example, the coordinates of the block IV d (left 3
(0, upper 30); (right 40, lower 40). For example, when a coordinate range is specified and keys A to E are set as shown in FIG.
Two types of tables such as Table 1 and Table 2 are created.

Then, it is checked which key is registered from the table based on the pressed coordinates, and only the registered keys are compared in range from the table to determine the input key. When portion of this time is pushed, the coordinate input unit 1 ₁₃ is to output a coordinate signal of the pressed portion, the input coordinate extraction unit
Is output only one of them the coordinate by one _14, so that the block is identified. For example, block VI
II b is pressed and one of the coordinates in the block (75,18)
Is input, it is known from the coordinate values that the block is a block of VIIIb, and it can be seen from Table 2 that the keys (3) and (5) are registered. From Table 1, the key (3) corresponds to the key C, and the key (5) corresponds to the key E. However, since the detected coordinates are (75, 18), the key E does not correspond to these coordinates. Therefore, since the key C falls within the coordinate range, the key code C is output. The present invention is characterized in that a key code is directly output instead of outputting a coordinate signal as in the related art. It also checks which block is pressed, checks which key is registered in that block, and determines which key code to output from that data. , All keys are sequentially searched, and a portion pressed at a higher speed than that which has been converted to a key code can be specified.

In FIG. 2, the block of the key C is also overlapped with the keys D and E, but in such a portion, the search priority is determined as shown in Table 1, and the key code is determined in that order. Just do it. The search order in Table 1 indicates this priority.

FIG. 4 is a view showing another embodiment, and an expansion card 4 is shown.
The upper left corner and the lower left corner are cut diagonally, and the cut portion is the center line 4 ₂ of the expansion card mounting hole.
The portion corresponding to the upper, is provided transmitter 4 ₁ and the receiver 4 _3. Also attach the transmission unit 1 ₂₁ in the portion corresponding to the receiver 4 ₃ receiver 1 ₂₀ in the portion corresponding to the transmitter 4 ₁ a on the center line of the body 1. In this case, the receiver 1 ₂₀
And the transmission unit 1 ₂₁ is non-directional, the transmission of the expansion card side portion 4 ₁
And the receiver 4 ₃ has to have a receiving portion 1 _20, facing the transmitter 1 ₂₁ directional.

In thus constructed apparatus, the transmission unit 4 of _the expansion card side is provided at the center line of the hole for mounting, the main body side of the receiving part
Since 1 ₂₀ is provided on the center line of the main unit, even if there is play within the allowable range of the mounting device when installing the expansion card,
Directional deviation is less likely to occur as compared with the case where it is attached to another part.

In FIG. 4, the expansion card is cut off at the upper left corner, but may be formed at the lower left corner. Also, as shown by a dotted line in FIG. 4 (in the vicinity of the center of the left end in FIG. 4). ) A V-shaped notch may be provided, and a transmitting / receiving unit may be provided in that portion. Also, the portion where the transmitting / receiving unit is attached is not linear as shown in FIG. 4, but if the convex chamfer shown in FIG. Reception becomes easier. Further, by performing a concave chamfer as shown in FIG. 5 (b), energy can be concentrated on the receiving element, and the efficiency can be further improved by using a reflective coating or a reflective plate on the cut surface.

Figure 6 (a) is a diagram showing another embodiment, the display unit 1 ₁
Is shown. The display unit 1 ₁ the display unit 1 of the main body side
_22, is configured from the display unit 1 ₂₂ detachably display enhancement unit 1 _23. Display unit 1 ₂₂ of the body side and a display device 1 _22b, the connecting portion 1 _22c of the liquid crystal or the like composed of a touch panel 1 _22a, transmission type to allow character input by handwriting. Display enhancement unit 1 ₂₃ is constituted by the light emitting device 1 _23a, battery 1 _23b, the connecting portion 1 _23c, claw 1 _23d for engagement with the display portion 1 ₂₂ and the display emphasizing portion 1 ₂₃ of the main body.

When the display unit 1 ₂₂ In a device constituted as above is mounted on the display emphasizing portion 1 _23, the connecting portion 1 _22c and the 1 _23c are connected, illuminated by the software from the main body of the CPU via the connecting portion Is turned on and off. The display highlighting unit ₁₂₃ uses a light emitting device,
It may be a reflector.

The display unit since 1 ₂₂ display element using a transmissive type, FIG. 6 (b) as shown in the display emphasizing portion 1
By removing ₂₃ , it can be used as an OHP sheet. In this way, the display screen can be enlarged and projected, so that it is suitable for many people to watch at the same time.

FIG. 7 is a block diagram showing another embodiment. In the figure, when the display direction is designated by the display direction designation means _12a , the signal is transmitted to the switching table _12b and the display switching means _1a .
Supplied to _2d . Therefore signal for display output from the display RAM 1 _2e is supplied to the display device 1 _2f while being direction change, is displayed. Therefore, even if the screen is turned vertically or horizontally by the holding method of this device, the display direction is normal for the operator.

The switching table _12b stores a key code suitable for the display direction, and the key code is read out according to a designation signal from the display direction designation means _12a . On the other hand, the direction key is pressed while viewed from the operator.
That is, when the cursor is to be moved upward, the operator presses a cross-shaped directional key and presses an upper part thereof. As a result, a signal corresponding to the position is output from the direction key.
Then, as described above, the key code in the direction designated by the display direction designation means _12a is output from the switching table _12b , and this key code is as shown in Table 3 for example.

In other words, the figure displayed as a solid line in FIG.
When used in a state rotated by degrees, the orientation of the screen also changes by 90 degrees as shown by the dotted line in FIG. Therefore, if you have to defeat the right, the key that was normal moves the cursor with the cursor keys 1 ₂ to the left (key symbol B) is to play a role above this time direction. For this reason, if as is changed role of the cursor keys 1 ₂ depending on the orientation of the screen as shown in Table 3, even the user changes the orientation of the screen without having to pay any attention, always the cursor keys The key operation should be performed according to the physical position of.

FIG. 9 is a flowchart showing the operation, and shows a state in which a predetermined table is selected according to each direction.

FIG. 8 shows a specific example of the display direction designation means. A contact sensor is provided on the back side of the hatched portion, and a designation signal is output from this sensor. That is,
Since it is possible to know which position is held by the sensor, the orientation of the screen is automatically identified based on the signal. In this case, it is more convenient to provide the predetermined input keys at the hatched portions.

[Effects of the Invention] As described above, the first invention realizes the state of pulse repetition or constant level pulse according to the level of the information signal. Therefore, only when the signal is transmitted from the transmission side, However, since an electrical change occurs, and no electrical state change occurs during the other periods, a device with extremely low power consumption can be realized if, for example, the circuit elements are formed of CMOS. In the second aspect of the present invention, since there is a pulse whose state change is small at the time of transmission, at least the portion is modulated by a pulse having a period much shorter than the period of the pulse, so that there is an effect that reliable information transmission can be performed.
